FAIRFIELD prefixes in area code 641
NANPA records 9 assigned NXX blocks to rate center FAIRFIELD in area code 641, 1.5% of the 584 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 6 holders hold those blocks, the largest being WINDSTREAM IOWA COMMUNICATIONS, INC. - SYSTEMS (4), LOCAL TELEPHONE DATA SERVICES CORP. (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2001-05-15 and the most recent 2024-03-14. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 203, 207, 208, 223 – overlay codes cover the same geography, so a rate center is served by all of them.
